Wolfson drivers not in next Raspbian update

wilsonkins over 11 years ago

It appears that the Wolfson drivers will not be in the next Raspbian update.

HifiBerry and IQ Audio I2S devices are supported. No Wolfson support until they submit a PR.
(from Raspberry Pi • View topic - Next firmware tree is now 3.12)
I hope someone from Wolfson reads this and follows up.

    Got this tweet from Raspbmc (Sam Narco) XBMC 13.0 "Gotham" for #Raspbmc is here: http://bit.ly/1fLMco1

     

    So no need to do anything but get new image or update and existing Raspbmc install.

    Has anybody actually tried this?  If so, could you summarize what needs to be done to make it work?  I just installed XBMC Gotham this evening and was unable to get it to work with my Wolfson card.

    I'll keep looking for links. What is your desired setup with XBMC? Just curious as a $5 USB Sound card card can deliver the same audio quality out. Here's a good understanding of what this card is compared to a USB sound card. https://www.youtube.com/watch?v=VU-JMVkbCP8&feature=youtu.be I am working on a write up as we speak and testing it out.

    I did see this post on Raspbmc from 4/14/2014 so it is coming I would follow this post and possibly recommend Raspbmc as it the only build I am aware of that is building in support. Please let me know if the other builds also offer support or intend to Raspbmc  » New Raspbmc update!

     

    I’m adding support for the following sound cards:

    • Wolfson Microelectronics Raspberry Pi Module – Wolfson’s patches for this had issues, so I’ve done my best to manually resolve these myself. I have reached out to a developer at Wolfson who tells me patches will be released in the future.

    Here is the best solution I can find

     

    The Wolfson audio card doesn't work with the official raspberry pi kernel, and their patches don't apply to the current kernel tree (you have to apply them to a tree from before Christmas).I think your only possibility is to use the supplied sdcard image they distribute, and then follow this:http://www.raspberrypi.org/forums/viewto...61#p520212to get raspmbc working. Note, this is a hack and you will find things that don't work (e.g. updates), but I don't think there is a better solution for now.



    Post found How do I get a wolfson audio card working in Raspbmc?

    Element14 or Woolfson Do you have a comment on this. At the moment I cannot use the card I bought as I need to run it with the current Kernel.

    I think in order to be of any assistance what requirements do you exactly need. What benefits over the older Kernel would you receive vs building it off the newer Kernel. (Note newer Kernel does not always equate to making your project better. Need to see what improvements were made.) Yes there does need to be integration into the default Raspbian images, etc.. But there are almost always options available through a Google search where work outside an official release results in what you need.

     

    By defining why you need to run it with the current Kernel they can answer if any updates that do come out will address your particular need.

    The Woolfson card is just part of my system. I need to keep other bits up to date. Having a system where I cannot run apt-get update and / or raspi-update is unacceptable.

    You have identified one problem raspi-update? I am not familiar with this I am going to guess you meant rpi-update. rpi-update will update you to the development Kernel. This is not intended for general use. But for the Linux dev's to test out the newer builds to see what bugs need to be discovered before being released into the general public. It's an advanced update utility and I strongly discourage anyone from using it if they want the most reliable tested kernel running on the Pi.

     

    Here is a quote from recantha's blog: http://www.recantha.co.uk/blog/?p=7316

     

    "As others have commented, rpi-update is useful if you want the latest, latest, latest version of the firmware, but does carry with it a few risks to the stability of your system."

     

     

    This is why you will see files inside this firmware being updated almost daily. Yet the official image is released only a few times each year.

     

    https://github.com/raspberrypi/firmware

     

    https://github.com/Hexxeh/rpi-update

     

    Updating for the sake of updating is never recommended unless your willing to post what issues you encountered and downgrade or help resolve the issues with the new firmware.

     

    No developer should be blamed if raspi-update causes a conflict as they may have just barely downloaded it and began to work on a resolution. kernel: Bump to 3.12.19 is Three days old just how fast a resolution to a developers hardware or software is acceptable?

     

    apt-get update doesn't do anything that should break your system:

     

    apt-get update doesn't actually install new versions of software.

    • apt-get update downloads the package lists from the repositories and "updates" them to get information on the newest versions of packages and their dependencies. It will do this for all repositories and PPAs.


    • Used to re-synchronize the package index files from their sources. The indexes of available packages are fetched from the location(s) specified in /etc/apt/sources.list. An update should always be performed before an upgrade or dist-upgrade.

     

    • apt-get upgrade will fetch new versions of packages existing on the machine if APT knows about these new versions by way of apt-get update.

     

     

    If using apt-get upgrade. Always pay attention to what packages have been updated and report a package that has possibly broken a known working feature. Again downgrade that app and await an official update.

     

    What is holding up the PR Documentation the Foundation needs is unclear and yes Wolfson should act as quickly as possible to get their card into the official Current Release of Raspbian. But as we are unaware of what steps they need to resolve at best we can hope for an update to their progress.

     

    The original question of this thread comes from this post Raspberry Pi • View topic - Next firmware tree is now 3.12

     

    If you notice it was stated the firmware would come out sometime this month I am not sure if it has already or if it is still in progress. Once Wolfson finishes their PR the Foundation will gladly update and include it very quickly.

     

    If you are using this Kernel Dom wrote "Note: this tree is aimed at testers. There could be missing kernel modules, or things that don't work. If you find any problems, then report here, or create a github issue."

    Wolfson was commented on and he replied what is needed. This was less than 30 days ago.

    Wolfson has been taken over by Cirrus Logic. See this link http://www.bbc.co.uk/news/uk-scotland-scotland-business-27202322

     

    The article says;

     

    "Wolfson has reported losses recently due to volatility in supplying that market.

    It has been shedding staff to bring its costs down"

     

    That may have something to do with lack of progress on getting the drivers included in the official Raspbian distribution. If the card is not considered a priority by Cirrus then we may be waiting a long time for anything to happen.
